ABSTRACT:
An integrated optical pickup and a manufacturing method thereof, and an optical information storage system including the pickup. The integrated optical pickup includes a light source; a main photo-detector, which receives light emitted from the light source and reflected from an optical information storage medium; a light-collecting and optical path separating member, which focuses light emitted from the light source on the optical information storage medium and separates an optical path of light incident on the optical information storage medium from an optical path of light reflected from the optical information storage medium; and an optical bench, which is coupled to the light-collecting and optical path separating member, an optical path being formed between the light source and the main photo-detector, and the light-collecting and optical path separating member, and the optical bench and the light-collecting and optical path separating member being respectively formed on a wafer and then obtained by being separated into a plurality of assemblies.
